Yup, Speedway 17. It's now owned by someone else, same idea, called Velocity 17. Nothing like a greased oval track and greased tires. Man that place was fun
The main issue with venting nitro is during the winter. It would be so cold inside there that the benefits of being indoors would be outweighed by the discomfort. In the summer it's another story. But in all honesty, I think it should just start as electric only to get the ball rolling, and get the track established. Once there is a good following, and enough interest, then I would look into trying to get venting for nitro. No need to be overwhelmed with getting the nitro things approved on top of everything else that needs to be approved right now just to get the doors open.
